Our verdict on ELAN
ELAN is desktop software for annotating and analyzing audio and video recordings, with a particular fit for language, sign-language, gesture, and multimedia corpus research. It supports time-aligned annotations linked to video frames, multiple annotation tiers, hierarchical tier relationships, controlled vocabularies, and synchronized viewing against the media timeline. Researchers can also link up to four video files to one annotation document, making it suited to structured analysis of related media.
ELAN is published as open-source software under GPL 3, with a free plan and no paid tiers. It runs on Windows, macOS, and Linux, giving research teams flexibility across common desktop environments. Its export options support downstream analysis and sharing, including tab-delimited text, CSV, Praat TextGrid, WebAnnotation JSON, HTML, and other formats. Search across annotation data adds practical value when working with larger collections or revisiting specific labels and time ranges.
The product’s main strength is depth in hierarchical, frame-accurate annotation rather than visual markup or workflow management. It is a suitable choice for researchers who need controlled taxonomies, synchronized media review, multi-tier structures, and portable dataset exports without licensing fees. Teams that need drawing tools, approval workflows, or a browser-centered collaboration environment should choose a different product. ELAN is most appropriate when annotation structure and research interoperability matter more than project-management features.
